Phenotype Characterization Of Sas-7(Or1945) C. Elegans, Chase Reinert
Phenotype Characterization Of Sas-7(Or1945) C. Elegans, Chase Reinert
Student Symposium
The ability to form a bipolar spindle is crucial for accurate cell division. In the nematode C. elegans several genes have been described with roles in spindle assembly including sas-7. The centriole is a key organizer of mitotic spindles. The sas-7 protein is a centriole component that regulates centriole duplication, elongation, and assembly. To date, most work on sas-7 was using a conditional non-null allele. In this study, phenotypes associated with the loss-of-function sas-7(or1945) null allele were characterized. Homozygous sas-7(or1945) hermaphrodites have reduced brood sizes with no viable embryos compared to wild-type and heterozygotes. When they do produce embryos, they …

Zoos contain a wide variety of animals that each have idiosyncratic behavioral patterns, personalities and preferences. Unlike scientific literature, which tends to focus on the population, zoos take the wants and needs of individuals as priority. It would, thus, be beneficial for the zoo to have a detailed account of individual behavior throughout the day so the zoo knows how best to care for individuals. However, it is very likely that a few zookeepers watch over several animals at a time and have tasks to perform throughout the day. Watching and documenting specific behaviors at a specific time is a …

Familiarity And Its Impacts On Male Mate Preference The Sailfin Molly, Poecilia Latipinna, Abigail Doza, Alyssa Back
Student Symposium
Mating behaviors are an integral part of the life history and ecology of many species. Male mate preferences are an especially understudied area of research. We examined male mate preference for familiar and unfamiliar female fish in the sailfin molly Poecilia latipinna. We hypothesized that males would prefer familiar females as they may have been able to gather additional information concerning the female’s reproductive status. Males were isolated for a minimum of four days and then tested in a choice tank with two females of similar size. After the experiment, each male was randomly assigned to be with one of …
Wildlife Rehabilitation Internship At Ohio Wildlife Center, Chase Reinert, Cassady Wolfinger
Wildlife Rehabilitation Internship At Ohio Wildlife Center, Chase Reinert, Cassady Wolfinger
Student Symposium
Ohio Wildlife Center treats approximately 8,000 sick, orphaned, or injured native Ohio wildlife every year. Throughout the spring semester, we completed a three-month internship to learn all aspects of wildlife rehabilitation. During our time at the Ohio Wildlife Center, we learned basic handling skills of a variety of species, including orphaned animals. Spring is the busiest time of year and most of our time was consumed with doing intake exams and tube feedings of infant animals. In addition to the wildlife hospital, the Ohio Wildlife Center has a pre-release facility located in Powell. Once a patient is deemed healthy enough …
